Here is a question that i have on a test review and neither the book or the teachers examples are any help.(adsbygoogle = window.adsbygoogle || []).push({});

If 200mL of 0.800 molar HClO is added to 400mL of 0.200 molar Ba(OH)2 solution, the resulting solution will be ________M in Ba(ClO4)2.

I know that the answer is 0.133M

i know that the balanced equation is:

2HClO4 + Ba(OH)2 ----> Ba(ClO4)2 + 2H2O

The steps that she has given us to do are:

1. balance equation

2. reaction ration

3. Start

4. Change

5. After reaction

6. Final Volume of Solution

7. Molarity

If anyone could explain how this problem is worked i would be greatly appreciative.
